I have two Tripp-Lites at 2 different sites: a SMART2200NET (via serial)
and a SMART2200VS (via USB). Each has a Raspberry Pi 3B acting as the NUT
master for their respective environments. The RPis have run Jesse, Stretch
and now Buster & have been very stable for me. I've always used the
Raspbian packaged version of NUT. Since you've validated the UPS and NUT
with another system, makes it look like the RPi might have an issue--I
wonder about the SD card, might it be the cause of your issues? Most of my
RPis are using SanDisk Extreme 16GB (SDSQXNE-016G-GN6MA) SD cards which
have seemed to be rock solid.
